were puting in a z6 into a VX and i have a little problem. the car has four plugs going to the ecu but the z6 harness comes w/ only three. what do we need to do ? and also how do you switch from a 5 wire o2 sensor to a reg. 4 wire sensor.

 

just use the 3 plugs.

there's also a link for the honda-tech article in that thread.

 

well, if you are using a chipped ecu disable o2 heater and just run a 1 wire o2, or disable it alltogether like i did you will have to w/ boost anyways. im running my z1 w/ no o2.

 

Isn't the 5 wire o2 sensor more or less a wideband? Someone told me that once, but I could never verify it

 

it is a wideband, but i dont think anybody has found a way to use the OEM sensor in an aftermarket setup yet.

 

well i got all of the wires switched around and everything, so ill see if everything works like it should.

thank you guys

 

good luck, that swap never works the first time, but good luck.

 

anyone have any idea what this is for.

 

looks like evap purge solenoid for the vx. mounts on the firewall.

 

nope, thats actually the vacuum control solenoid for the EGR valve. ditch all that stuff.
